Many bracelets of this kind were worn during the 70's to pay tribute to soldiers who were either MIA or POW's in Vietnam. The bracelets were worn until the named soldiers came home. If memory serves, the white on blue stars were placed on the bracelet when the soldier returned to the US. Although I did not support the war, I did want to show my support of the troops. I wore this one during my freshman year at college. Capt. Kerr was captured in January 1967 and returned home in March 1972.
